边坡深孔监测位移曲线异常的原因分析及纠正措施

基于深孔测斜的基本原理和工程实践,根据大量边坡深孔位移监测的工程实例,归纳、总结了典型性的异常深孔位移监测曲线,深入地剖析曲线异常的原因及纠正措施;并对测孔布置、钻探、监测数据采集和处理等影响深孔位移监测结果的关键步骤,提出明确的控制要求,确保深孔位移监测的准确性及可靠性.

Analysis of Typical Displacement Curve of Slope Deep Monitoring

Based on the basic theory of deep hole surveying and the engineering practices,this paper generalized the typical abnormal deep hole displacement monitoring curve from large amount of engineering examples about deep hole displacement monitoring on slope,and further analyzed the causes of the abnormals and the corrective measures.In relation to the key steps affecting the monitoring result,including hole arrangement,drilling,acquisition and processing of the monitoring data,definite control requirements were proposed to ensure the accuracy and reliability of the monitoring.
